What is DSpice?

---

DSpice (Designing Circuits and Simulation by SPICE) is an open-source tool designed to streamline the modeling of analog components and the simulation of electronic circuits. It leverages ngspice (the open-source successor to the classic SPICE engine) as its core simulation backend. The main objectives and features of DSpice are:

• Custom Modeling: Creating new SPICE models for various electrical components.
• Symbol Design: Designing and managing custom schematic symbols for these models.
• Schematic Capture: Drawing and designing circuits using an intuitive CAD-style schematic editor.
• Circuit Simulation: Executing simulations (OP/Tran) seamlessly using ngspice.
• Waveform Visualization: Analyzing and presenting simulation results through a dedicated waveform viewer and Prob.

News

What’s changed in versions

• Interface of DSpice created using ElectronJS (v34.2.0) and NodeJs (v22.13.1), enabling a modern cross-platform desktop experience.
• Using ngspice (v46), which provides a robust library for analog and mixed-signal circuit simulation.
• Support for both analog models, providing flexibility for various use cases.

Future Work / Roadmap

• Implement AC (Alternating Current) Analysis.
• Develop a comprehensive Options/Settings Dialog.
• Create a Library Management Dialog for better component organization.
• Expand the component library with additional semiconductor devices and digital models.
• Export analysis results to standard formats (e.g., CSV files).
• Integrate Verilog (Verilog-A/AMS) for mixed-signal (analog and digital) modeling.
• Embed a Python scripting engine for automation and custom extensions.
• Extend pplication compatibility to support multiple operating systems, specifically adding native builds for Linux and macOS.

Note

To create a DSpice application from the src directory:

1. Download and install Node.js from the official website: https://nodejs.org/
2. To update ngspice, download ngspice and add it to the DSpice\ngspice directory.
3. Navigate to the src directory and run the following commands:

   npm install
   npm start
